EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
  • Cough.
    Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.

  • SKIN
  • Redness.
    Protective gloves.
    Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES
  • Redness.
    Safety spectacles.

  • INGESTION

  • Do not eat, drink, or smoke during work.

    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P3 filter respirator for toxic particles).
    Separated from incompatible substances (see Chemical Dangers).
    Unbreakable packaging; put breakable packaging into closed unbreakable container.

    PHYSICAL STATE; APPEARANCE:
    RED DELIQUESCENT POWDER.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride (see ICSC # 0163). Reacts violently with iron pentacarbonyl and zinc causing explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: ppm; 0.01 mg/m3 (as TWA) (ACGIH 1995-1996).


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

    INHALATION RISK:
    Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

    EFFECTS OF SHORT-TERM EXPOSURE:



    PHYSICAL
    PROPERTIES
    Melting point (decomposes): 100C
    Relative density (water = 1): >1
    Solubility in water: very good
    ENVIRONMENTAL
    DATA

    N O T E S
    The name of rhodium chloride is often used both the hydrated and the anhydrous form. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
